Preparation and Characterization of Non-woven Blend Membrane from CA and PES in DMAc/LiCl

Abstract

In this article, in order to improve the hydrophilicity and anti-fouling ability of the pure PES membranes, CA was introduced in N,N-dimethylacetamide/lithium chloride with non-woven fabric as support. The influence on PWF was studied, and the preparation condition was optimized as follow: PES, 18 wt%; PVP K30, 4 wt%; CA, 3 wt%; Evaporation time, 20 s. The characteristics of membranes were studied by means of SEM, anti-fouling performance and compatibility. The compatibility results showed CA/PES membrane was a semi-compatibility system. The results indicated that the performances such as hydrophilicity and anti-fouling ability were improved remarkably with the addition of cellulose acetate.
